I'm working on a Vue + typescript
project. I want to use process.env.var_name
to adjust the project is in development mode or production mode, just like
const isProduct = process.env.APP_ENV === "prod";
; however I got an error below. I never meet this error before, so could any one give me a clue why this would happen so I can try to figure out what happend in the project and then fix it.
If you are using Vite, use import.meta.env
instead, process.env
is removed.
And make sure variables start with VITE_
in .env
file.
VITE_SOME_KEY=123
